HENRY PORT AND EUGENE SURGI, OF NEW ORLEANS, LOUISIANA.

iaoor oft SHOE;

Specification of Letters Patent No. 30,419, dated October 16, 1860.

Tocll whom it may concern;

Be it known that we, HENRY Pom and EUGENE SURGI, both of the city of NewOrleans, in the State of Louisiana, have invented certain new and usefulImprovements in the Manufacture of Boots and Shoes; and we herebydeclare that the fol lowing is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making partof this specification, in which Figure 1, represents a perspective viewof the inside of the sole of a boot, with a portion of the upperleather; Fig. 2, a bottom view of the same, divided into two parts; Fig.3, a bottom view of the same with a heel and shank of different form andconstruction; Fig. 4:, a perspective view of the heel and part of theshank shown in Fig. 3; Fig. 5, a plan view of a metallic skeleton plateor frame; Fig. 6, a plan view of a similar plate but divided intosections; Fig. 7, a perspective view of the inside of a heavy sole,divided transversely into two parts for the purpose of showing the edgeof a metallic plate S; Fig. 8, a transverse section in the line X X ofthe heel shown in Figs. 3 and 4 and Fig. A a form of rivet.

The letters of reference indicate the same parts in the differentfigures.

To enable others skilled in the art to manufacture boots and shoesaccording to our improvements we subjoin the following description.

The upper part of the boot or shoe is made and prepared in the usualmanner but is secured to the sole by means of tapering metallic rivets,passing through holes in frames of metal C, and through the uppers andsoles. The holes in the frames and soles are punched with suitablemachinery so that they shall correspond with each other. A last of metalor faced with metal is used, against which the rivets are driven, andfirmly clenched. A firm union of the uppers to the soles is thusaccomplished superior to that formed by the use of pegs or by stitches.The sole may be worn away to the plate before a separation can takeplace.

The plate shown in Fig. 6 is divided into sections for the purpose ofincreasing its flexibility when heavy soles are used. The cross bar inthe frame O is for the purpose of uniting the shank with the fore partof the sole by means of rivets or screws passing through holes in thebar and through the lap of1 the chamfered edges of the shank and so e.

A is the form of rivet we prefer in heavy work.

It is split at its entering end, and forks and spreads as it is drivenagainst a hard substance forming a secure clench as shown at d, Fig. 7.

The shank and heel in Figs. 1 and 2, are made of vulcanized india rubberin one piece without joints. The great facility with which this materialcan be molded into any desired form reduces the expense materially ascompared with leather, while its elasticity durability and waterproofqualities render the use of it for this purpose an important improvementin the manufacture of boots and shoes.

The shank and upper portion of the heel 0, Figs. 3, 4 and 8, are made inone piece of zinc or other metal. Both ortions of the heelare'elliptical in their orm, the lower part connected to the upper partby a screw 7, through its center. An elliptical flange is formed uponthe upper side of the lower portion which fits into a correspondingcavity g in the upper one o. Thiscavity is left for the purpose oflightness and of economy of material its form prevents the lower piecefrom changing its position unless the screw is slackened or removed forthe purpose of reversing the lower part, when worn on one side, as isfrequently the case. Changing the worn side of the heel to the oppositeside has a tendency to correct the fault in the tread of the wearer,which causes the heel to wear faster on one side than the other.

In heavy soles a thin plate S, Fig. 7, of metal of the same size as thesole may be placed between two layers of leather and rivets or smallscrews may be used passing through the soles plate S, upper leather andframe C to confine the whole together.

What we claim as our invention and desire to secure by Letters Patent isThe metallic skeleton plate or frame C, when used in combination withthe sole and upper leather in the manner and for the purpose specified.
